Legend has it that when Troy fell, women prevented their husbands from retreating by burning their boats.

Here is an example of how to use this idiom today:

"Look. I know you want to go abroad because you like it there. But by selling your house and giving up all your business here you are burning your bridges. Don't you think someday you might want to come back here?"
